Memory leaks.

We've been running 1080b linux servers for some time without a reboot now, 9 servers in total on 2 SMP machines.
Initially it all ran fine, low pings, no lag, happy players. But after a while i started to notice switching maps was taking awfully long, 
sometimes over 30 sec. Some players assumed the server crashed and went to another, which is off course every GSP's nightmare. 
Here's what seems to have caused it:

   PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
 24738 ut2003    19   0  120M  95M  3688 S    33.6 18.9 505:23 ucc-bin
 24726 ut2003    15   0  209M 143M  5912 R    29.1 28.3 458:24 ucc-bin
 24748 ut2003    17   0  104M  78M  3644 R    21.2 15.6  1171m ucc-bin
 24715 ut2003    14   0  244M 142M  3584 S    11.4 28.1 546:56 ucc-bin

With freshly booted servers it looks like this:

   PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
 15908 ut2003    20   0 70048  68M  5904 R    52.5 13.5   9:39 ucc-bin
 15851 ut2003    17   0 73556  71M  5900 S    50.7 14.2  30:05 ucc-bin
 15856 ut2003    16   0 74236  72M  6084 R    48.4 14.3  32:00 ucc-bin

This didn't seem to happen back with 1077, but that might also be simply because in the first few days the servers were restarted often for 
testing new settings. They run various gametypes, and get a lot of usage. Tried restarting one with the relaunch command, didn't help.
For now as a remedy the servers will be restarted daily in the early hours. Seem's we're dealing with a very nasty bug here. Is anybody else 
experiencing this?
