So what's going on during the frequent 11-second gaps? (Was Rosemary Woods
here?)
They are not only frequent, they are also totally regular. Looks like a
regular gap of 10 s + some fraction, that looks like 10 or 11 just
because of the logfile stamp resolution.
Might want to redo the strace with the -T option to show the time spent inside
each system call.
During the Tomcat stall phase there are thousands
and thousands of stat64, access, lstat64 calls to
the same class files (and directories above those
files) across pages on all four sites.
Actually it is totally regular : stat, access, lstat, stat, then 10.xxx
delay, then again stat, access, lstat, stat, 10 seconds +.
What in this directory path is (are) a symlink(s) ?
/home/sites/ims/jcms/webapps/ROOT/WEB-INF/classes/org/apache/jsp/test6_jsp.class
and to what does it (they) point ?
And how is this different from the other 2 systems that work fine ?
