Hi, It seems we still have problems with ipcrm not being able to remove shared memory segments. On a 4.7-STABLE system: # ipcs -a Message Queues: T ID KEY MODE OWNER GROUP CREATOR CGROUP CBYTES QNUM QBYTES LSPID LRPID STIME RTIME CTIME Shared Memory: T ID KEY MODE OWNER GROUP CREATOR CGROUP NATTCH SEGSZ CPID LPID ATIME DTIME CTIME m 29622272 0 --rwarwarwa anders users anders users 2 393216 41265 4112411:25:34 11:25:57 11:25:34 m 30539777 0 --rw-r--r-- root wheel root wheel 1 110592 41124 4126511:32:25 11:32:25 11:32:25 m 7864322 0 --rwarwarwa anders users anders users 1 393216 2372 27122:18:09 23:04:03 22:18:09 m 2949123 0 --rwarwarwa anders users anders users 1 460800 2372 27123:02:21 23:04:03 23:02:21 m 1114116 0 --rwarwarwa anders users anders users 1 112320 2372 27123:02:21 23:04:03 23:02:21 m 655365 0 --rwarwarwa anders users anders users 1 78400 2372 27122:59:51 23:04:03 22:59:51 m 1572870 0 --rwarwarwa anders users anders users 1 37600 2372 27122:59:51 23:04:03 22:59:51 m 393223 0 --rwarwarwa anders users anders users 1 36000 2372 27122:59:51 23:04:03 22:59:51 m 2752520 0 --rwarwarwa anders users anders users 1 112320 2372 27122:59:51 23:04:03 22:59:51 m 131085 0 --rwarwarwa anders users anders users 1 748800 2372 27122:58:59 23:04:03 22:58:59 m 8192015 0 --rwarwarwa anders users anders users 1 748800 2372 27122:58:49 23:04:03 22:58:49 m 8060944 0 --rwarwarwa anders users anders users 1 748800 2372 27122:59:02 23:04:03 22:59:02 (..)

Is anyone with kernel-foo thinking about fixing or looking into this? Cheers, -- Anders.
