Every since I updated Openfire from 3.7.1 to 3.8.2 a couple weeks, I have had an issue with Openfire leaking file descriptors over time. I have to restart the service every 3-4 days it seems or it stops functioning as it hits the 1024 file limit on open file descriptors. This is on an Ubuntu 8.10 server with the following install of Java:
java version “1.6.0_14”
Java™ SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot™ 64-Bit Server VM (build 14.0-b16, mixed mode)
Running lsof against the running process for Openfire reveals many lines like the following:
java
9292 openfire 1013u IPv6
26142468
TCP example.com:5369 (LISTEN)
java
9292 openfire 1014u IPv6
25781341
UDP example.com:5358
java
9292 openfire 1016u IPv6
25787324
UDP example.com:5359
java
9292 openfire 1017u IPv6
26206580
TCP example.com:5372 (LISTEN)
java
9292 openfire 1019u IPv6
25811610
UDP example.com:5361
java
9292 openfire 1021u IPv6
25864846
TCP example.com:5364 (LISTEN)
java
9292 openfire 1022u IPv6
25858168
UDP example.com:5363
At that point, everything starts failing until Openfire is restarted.
