I am using qlogic driver patch with this kernel. Every time I insert qlogic driver my as_arq pool size increases by 2000 objects of each size 76 bytes. I have kgdb setup and I tried to put break point in various function in as_iosched.c to see if I can see where it is getting allocated, but It never hit the breakpoint. Can anyone tell me whether its as-i/o scheduler problem or something in qlogic driver? How do I debug is problem? After doing just insmod/rmmod for 20/30 times my machine runs out of free pages. If I dont try to insert qlogic driver my system runs fine for days without any problem. Following is the output of /proc/slabinfo for as_arq after doing insmod/rmmod. Any help as to how to debug this problem is appreciated. Thanks Amit [root@Host200-w2k root]# cat /proc/slabinfo |grep as_arq as_arq 6251 6300 76 50 1 : tunables 32 16 0 : slabdata 126 126 0 : globalstat 165249 6300 1708 1538 0 1 82 : cpustat 245396 11366 247012 3502 [root@Host200-w2k root]# cat /proc/slabinfo |grep as_arq as_arq 8291 8300 76 50 1 : tunables 32 16 0 : slabdata 166 166 0 : globalstat 167299 8298 1749 1539 0 1 82 : cpustat 247381 11530 247121 3502 [root@Host200-w2k root]# __________________________________ Do you Yahoo!?
