Hallo,

Mijn tomcat server reageert niet meer. Het aantal file descriptors neemt opeens toe. Waar duidt dit op?

Groeten,

Marnix

Dear Marnix,

A sudden increase in file descriptors can mean a lot of things, since they are used for files, pipes, sockets and other obscure OS-related resources.

80 file descriptors open is not very many, if you consider that each JAR file and each socket uses a file descriptor.

I've seen peaks in file descriptors happen when I shut down the database without stopping my application servers. Does you database show any sign of trouble, or was it restarted around 16:00 hours?

You could have a look with lsof, sockstat or netstat to see what these file descriptors are used for.

Any messages in the Tomcat logs?

Dear Marnix,

Did you find the time to check the logs?
