Hello,
Running OpenJDK-7.2.6.1 under Linux/amd64. Since about a month ago Mafia began to allocate and never release a massive number of SysV shared-memory segments, pretty quickly exhausting the limit and preventing other programs depending on shm - for example anything Qt-based - from working properly. The problem is definitely related to Mafia, as I have used the same JRE on the system to launch several other Java applications and none of them do the same.
Here is an example log of shared-memory allocation over time, with Mafia doing nothing but displaying chat. Actually using Mafia considerably speeds up shared-memory allocation - I have just hit over 20,000 allocated segments in less than one hour.
09:15:32 just before starting Mafia
segments allocated 12
pages allocated 18080
09:18:08

pages allocated 9855371
14:22:50
segments allocated 32768
pages allocated 9855248
16:26:22 immediately after quitting Mafia
segments allocated 15
pages allocated 21280
As usual, let me know if you need any more information.
