--------------------------------------------------------------
Linux: Red Hat Enterprise Linux ES release 3 (Taroon Update 9)
jdk1.5.0_11
tomcat 6.0.14
libs:
jsf-facelets_1.1.14.jar
myfaces-api-1.2.2.jar
myfaces-impl-1.2.2.jar
trinidad-api-1.2.5.jar
trinidad-impl-1.2.5.jar
The problem seems to be the first request of each client (in my case this is
the login-page). Whenever a new client requests its very first page from the
webapp the number of open file descriptors raise by round about 45 - 50. If I
perform a System.gc() manually (via jconsole) it decreases to 45, which might
be normal for our configuration.
So if there are requests from approx. 20 different clients - without Full GC in
between - the limit of 1024 open file descriptors is reached.
If JMX is enabled a workaround could be to check the MBean
"java.lang:type=OperatingSystem" (Attribute "OpenFileDescriptorCount" ).
Whenever this MBeanAttribute reaches a certain value (i.e. 500) perform a
System.gc().
I would be great of this issue could be solved in near future.
Thanks.
