Subject CacheManager problem
Date Thu, 08 Nov 2007 10:30:43 GMT

Hi all,
I have a problem regarding CacheManager size under heavy load and system
slowdown.

CacheManager start with:
16:28:13,476  INFO CacheManager:125 - resizeAll size=78

after it grows too much:
17:28:23,079  INFO CacheManager:125 - resizeAll size=122
17:28:24,143  INFO CacheManager:125 - resizeAll size=224
17:28:25,270  INFO CacheManager:125 - resizeAll size=382
17:33:24,567  INFO CacheManager:125 - resizeAll size=468
...
19:09:35,674  INFO CacheManager:125 - resizeAll size=162467
19:11:03,601  INFO CacheManager:125 - resizeAll size=162737
19:12:33,840  INFO CacheManager:125 - resizeAll size=163095

Then system starts slowdown and some errors occured.

I use a Session Pool to share some session to 'read-only' users. Creation of
the pool that starts with webapp and sessions are never logged only (only in
case of errors and recreated) to be shared among users. I share 15 sessions
for each of the 2 workspaces I use.

Please can anyone address me to an analysys of this problem?

I use JR 1.3.1 patched with JIRA-905 patch to avoid duplicated entries in
index searches.
Server is Oracle 10g on Solaris. Db used is also Oracle10g.

Another point, I have a big collection of blobs in db (but I don't thinks it
could be the problem).

It's pretty urgent.  

Thanks a lot in advance.

BR,
Andre.
