Wed Feb 8 15:51:34 [mongosMain] Listener: accept() returns -1 errno:24 Too many open files
Wed Feb 8 15:51:34 [mongosMain] ERROR: Out of file descriptors. Waiting one second before trying to accept more connections.

Started receiving the above when an ETL went rogue. Looks like the issue is ulimit.
[mongodb@my07apl01 ~]$ ulimit -n
1024

I am working with the server team to raise it. However, is there anything I can do to regain control of this prior to getting that changed. I haven't been successful in pulling up the mongos shell.

Thanks!
