Hi David, thank you for the info. Looks like you really have unexpected
long-lasting task(s) running, which occupy all the http-listener threads. The
log message just signals about that. Once server becomes unresponsive next
time - pls. take a thread dump using "jstack" utility. Most probably you'll
see all the http-listener worker threads blocked at some operation...
according to [1] log, I'd think it's DB related. Pls. share the threads dump
once you have it. Thanks. WBR, Alexey. [1]
