## Expected Behavior I started a few weeks ago with a new instance of Graylog 3….0.2 on CENTOS7. I need this version because of the Airbus Wizard plugin for alerting. All was working well, with almost 5Gb of logs/day. I set Java memory to 10Gb. Elasticsearch is installed on another server, and running well. ## Current Behavior Since this morning, the server is becoming unstable without any reason and no change in the configuration. I'm currently unable to connect to the API. When I restart the graylog service, I encounter no error, but when I try to connect to the API, I have this message in the Graylog logfile : ``` 2020-07-14T16:44:39.787Z WARN [ProxiedResource] Unable to call http://Graylog_IP:9000/api/system on node <xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx> java.net.SocketTimeoutException: timeout at okio.Okio$4.newTimeoutException(Okio.java:232) ~[graylog.jar:?] at okio.AsyncTimeout.exit(AsyncTimeout.java:285) ~[graylog.jar:?] at okio.AsyncTimeout$2.read(AsyncTimeout.java:241) ~[graylog.jar:?] at okio.RealBufferedSource.indexOf(RealBufferedSource.java:355) ~[graylog.jar:?] at okio.RealBufferedSource.readUtf8LineStrict(RealBufferedSource.java:227) ~[graylog.jar:?] at okhttp3.internal.http1.Http1Codec.readHeaderLine(Http1Codec.java:215) ~[graylog.jar:?] at okhttp3.internal.http1.Http1Codec.readResponseHeaders(Http1Codec.java:189) ~[graylog.jar:?] at okhttp3.internal.http.CallServerInterceptor.intercept(CallServerInterceptor.java:88) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) ~[graylog.jar:?] at okhttp3.internal.connection.ConnectInterceptor.intercept(ConnectInterceptor.java:45) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:121) ~[graylog.jar:?] at okhttp3.internal.cache.CacheInterceptor.intercept(CacheInterceptor.java:93) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:121) ~[graylog.jar:?] at okhttp3.internal.http.BridgeInterceptor.intercept(BridgeInterceptor.java:93) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) ~[graylog.jar:?] at okhttp3.internal.http.RetryAndFollowUpInterceptor.intercept(RetryAndFollowUpInterceptor.java:126) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:121) ~[graylog.jar:?] at org.graylog2.rest.RemoteInterfaceProvider.lambda$get$0(RemoteInterfaceProvider.java:61) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:147) ~[graylog.jar:?] at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:121) ~[graylog.jar:?] at okhttp3.RealCall.getResponseWithInterceptorChain(RealCall.java:200) ~[graylog.jar:?] at okhttp3.RealCall.execute(RealCall.java:77) ~[graylog.jar:?] at retrofit2.OkHttpCall.execute(OkHttpCall.java:180) ~[graylog.jar:?] at org.graylog2.shared.rest.resources.ProxiedResource.lambda$getForAllNodes$0(ProxiedResource.java:78) ~[graylog.jar:?] at java.util.concurrent.FutureTask.run(FutureTask.java:266) [?:1.8.0_252] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) [?:1.8.0_252] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) [?:1.8.0_252] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_252] Caused by: java.net.SocketException: Socket closed at java.net.SocketInputStream.read(SocketInputStream.java:204) ~[?:1.8.0_252] at java.net.SocketInputStream.read(SocketInputStream.java:141) ~[?:1.8.0_252] at okio.Okio$2.read(Okio.java:140) ~[graylog.jar:?] at okio.AsyncTimeout$2.read(AsyncTimeout.java:237) ~[graylog.jar:?] ... 28 more ``` ## Steps to Reproduce (for bugs) No Idea on how to reproduce bug. And no idea how it happened. ## Your Environment * Graylog Version:3.0.2 * Elasticsearch Version:6.8 * MongoDB Version: * Operating System:CENTOS7 * Browser version:Firefox 68 All HTTP URI in server.conf are with local IP used to connect to Graylog.
