Hi All,

In a stable system with 2.6.14 kernel, which continuously sends/receive packets, I noticed an increase in slab size of around 1.5GB in 30 hours.
I see a continuous increase in number of task_struct and size-16384(thread info) object.

I use an application that uses SIGEV timer thread with time-out of 20 millisecs. Each time, upon expiry of SIGEV timer(20 millisecs), a thread start routine will run "as if" it were a new thread, to process the packets in the system.

Whenever the application is killed/restarted, all the task_struct objects are getting released.

1. Is there any known issue in 2.6.14 kernel for handling SIGEV timer thread ?
2.Will there be any issue in 2.6.14 kernel, in clean up of task_struct for application that creates/deletes threads at a rate of 20 millisec?

Thread creation/deletion are handled properly in the application. Still I am unable to figure out reason for memory leak.

Appreciate your inputs.

Thanks,
Sowmya
