Sorry for late reply but your JIRA notification hasn't reached me somehow...

Norman,
Nothing non-standard. I'm spawning 20 threads, which sequentially, independently process c.a. 40 read-data-only pages in a loop. Most of these pages use s:cache to avoid unnecessary RDBMS calls. In this scenario this cache is not being invalidated in any way, so after caches get populated requests are served pretty quickly. After each loop a new session is created (JMeter's cookie manager drops previous session context) and I let old session get expired after 5 minutes timeout. As soon as caches are ready I've got 50 requests/second served and this error (and in very marginal cases JBSEAM-2360 <no fix version set>) start appearing.

Pages data is backed by PAGE scoped beans, there are some SESSION-scoped utility beans (some of these with @Startup annotation) bound to every session. Nothing unusual here, and until I put some concurrency tests on this everything was fine. But now I have this issue as well as JBSEAM-2086 and (very, very rarely) JBSEAM-2360. This issue is still present after applying my workaround for JBSEAM-2086. Got 3-8 such exceptions per every minute.
