Looks like even when load balanced it blocks connections after time. Its all the exceptions im sure of it, no out of memory errors which is bizarre until i try and reboot the service which it logs all the jvm dumps because it hanged, ive kept the threadcount to 4 as setting it to the max it can do causes issues which was 2700.
This one is fairly bizarre as it wasnt an outofmemory error as i usually get, we load files from a network drive using a UNC name like so file:////computername/sharename jvm 2 | 2007/04/28 00:45:32 | java.io.IOException: The specified network name is no longer available INFO | jvm 2 | 2007/04/28 00:45:32 | at sun.nio.ch.FileDispatcher.read0(Native Method) INFO | jvm 2 | 2007/04/28 00:45:32 | at sun.nio.ch.FileDispatcher.read(Unknown Source) INFO | jvm 2 | 2007/04/28 00:45:32 | at sun.nio.ch.IOUtil.readIntoNativeBuffer(Unknown Source) INFO | jvm 2 | 2007/04/28 00:45:32 | at sun.nio.ch.IOUtil.read(Unknown Source) INFO | jvm 2 | 2007/04/28 00:45:32 | at sun.nio.ch.FileChannelImpl.read(Unknown Source) INFO | jvm 2 | 2007/04/28 00:45:32 | at org.red5.io.flv.impl.FLVReader.fillBuffer(FLVReader.java:319) INFO | jvm 2 | 2007/04/28 00:45:32 | at org.red5.io.flv.impl.FLVReader.fillBuffer(FLVReader.java:268) INFO | jvm 2 | 2007/04/28 00:45:32 | at org.red5.io.flv.impl.FLVReader.readTag(FLVReader.java:545) Dan Rossi wrote: > Seemed to kind of stablise for a while, however im looking at the > performance monitor and the page faults column is high, is this an issue > ?
