thanks, i will try INVARIANTS and WITNESS options and will try to get freebsd 6.0. it will be only tomorrow when i'll be able to do this because it is already evening and i will go to my office tomorrow only. in the mean time if the memory corruption is the problem then is there any option/configuration or possible thing i could do to make sure that the kernel quits or throws some messages or panics on the moment the corruption takes place rather than some time later when other program is affected by it. that way i could locate any bug in my code if present. thanks, kamal Xin LI <delphij@gmail.com> wrote: Hi, On 12/25/05, kamal kc wrote: [...] > Is the problem related to memory leaks or sleeping > on mutexes or some other causes. >From the backtrace you have provided, it looks like a memory corruption. In order to aid your debugging, you will want INVARIANTS and WITESS, etc. to be enabled. Also, if feasible, please consider using code from -CURRENT or at least RELENG_6_0, as there are more debugging aids that is likely to catch bugs early.
