Hi
Am sorry, clicked submit by mistake
The below is the actual problem
We are running into too many open files exception on our production tomcat
server for the last 2-3 days.
We have max threads as 150 and acceptCount as 100 and at one point of time all
the 250 threads are busy processing requests (due to application related
issues)
You only have 150 threads, not 250. 150 is not a large number & is in
fact lower than the default.
At 50-60 requests per second, you must serve each request within 0.3s
That number (0.3) is around an order of magnitude too small.
Mark
to
avoid queuing requests (ie, using the acceptCount queue). You should
avoid queueing requests.
At peak times, when all the threads are busy, new requests are rejected by
tomcat.
Expected.
Nearly 40 mins to 1 hr after the rejections begin, there are too many open
files exception coming on the tomcat server..
Maybe this is the real peak.
The number of file descriptors is 16384 and we are getting 50-60 requests per
sec.
What can be the root cause here.
Too many possible options, not enough info.
After rejecting a request, is the socket not closed immediately and this
results in pile up of open files or is there some other reason ?
Can any one help us in this regard ?
Please post the Connector configuration from server.xml. You may
obscure/remove passwords if present.

Thanks,
