I am not sure why CLOSE_WAIT should cause this.
Sitting here waiting for the presidential debate... cant wait to hear how
those two brain surgeons are going to save the world ;)
I dont know why it occurs but something is holding connections open...
possibly some low down socket function that should be cleared and is
not...
Because I cant imagine how one has that much control in TC normally over
sockets... I suspect you using something like NIO... or possibly its
something like hibernate not letting Db connectors go, or a cache...
something is holding stuff open in your code... and eventually it clogs
the system.
Very likely thru some subtle coding error, or buggy components... going to
have mess with the code and try figure out whats not letting go...
Normally difficult bugs to find...
Good Luck...
PS: I see you have a Apache in front...
Try this... setup the 8080 connector if you havnt already got it working in
TC... and go into TC direct... then check file handles....
If no problem, you know its Apache or the JK connector...
... will at least point you in right direction...
