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.
