On our environment we are observing a high number of threads waiting with the following stack:

(dump from http://jenkinsurl/threadDump )
The amount of similar waiting threads increases by 2 on every login and are not being closed leading to a "Too many open files" after a couple days, at that point 378 were waiting with the stack above.
Please let me know if any further information is required to help solve/reproduce this issue.
