[SNMP4J] Threads are being blocked in snmp4j 1.8 RC1

[varma datla]

Hi Frank,
I am using the snmp4j 1.8 RC1 library (multi-threaded, synchronous) in a tomcat application with 250 threads. Also using 3 retries and 500,1000,5000 as timeouts per request.
After a while, the whole application is blocked and  doing nothing. A JConsole lookup revealed that all the threads are waiting on org.snmp4j.Snmp$SyncResponseListener class. 

Any ideas?

JConsole  output:

Name: pool-1-thread-1 
State: WAITING on org.snmp4j.Snmp$SyncResponseListener at 676bc7 
Total blocked: 7,546  Total waited: 127,560 

Stack trace: 
java.lang.Object.wait(Native Method) 
java.lang.Object.wait(Object.java:474) 
org.snmp4j.Snmp.send(Unknown Source) 
org.snmp4j.Snmp.send(Unknown Source) 
..............

Thank you and I appreciate any suggestions to overcome this problem.

Varma
