Hi Frank, First of all many thanks for the direction provided by you. We were using JDK 7 u1 where we had the issue, & after updating to JDK 7 u9 we do not see the issue (or at-least the application has been running stable for 8 hours). We are using single instance of 'Snmp' where again the issue gets reproduced in JDK 7 u1.(but not in u9)
>From Java release notes, I'am trying to trace which of the Java issues between u1 & u9 that causes this problem, but could not find anything very relevant. Kindly share if you are already in possesion of the issue number/the root cause JVM bug. (Again, this happens only on multi-threaded application, 64-bit processor/OS) Also, do you have any suggestions on the recommended Java version considering SNMP4j library? (i.e., works stable across 32-bit, 64-bit, different OS'). Though we observed in JDK 7, could the older versions 5/6 also be vulnerable? Alternately, will increasing the socket buffer size avoid the problem totally irrespective of the JDK version? Since NIO channels are being used inside SNMP4j, how is it recommended to increase the send buffer size on windows? what value may be good enough (Application may use upto 15 threads to send SNMP Get sub tree at a time) Thanks in advance.
