Re: 3MB Memory Leak in KDrive Xfbdev
Hello All, I am able to fix the 3M memory leak. 1M as explained already and the other 2M was because of my mistake -one extra thread that I had launched and was not getting freed. However, I still see few kBs ~132kB of memory leaked in every 2-3 iterations of Init-Term Xserver. Note: In some iterations of Init-TermX there is 0 memory leak and some there is a chunk of 132kB. Also, I am still stuck with failure(Device or resource busy) is ioctl(fd, DISALLOCATE, vtno) in LinuxFini(). I doubt this for the 132kB leak. Can anyone help me out with this? Note: This ioctl failure happens only on target board (ARM) and not on x86. Any inputs related to above would be very useful to me.

BTW, I need a light weight server and KDrive being a stripped down version of Xorg, I am using KDrive. Also I did get some success in freeing 1M out of 3M memory that was leaked. This is achieved by calling mieqFini() at termination of Xserver. This function internally calls FreeEventlist() which frees the 1M memory allocated in InitEventList(). If anyone has any more idea of the memory leak in KDrive please let me know.

AllocNewConnection fails:: (fd lastfdesc)
Hello All, When I run Xfbdev server with IPV4 on a target machine, for initial 3-4 mins everything is fine and I can launch clients. However, after some time, below thrift error messages are generated by the system from some other module *Thrift: Thu Jan .TServerSocket::listen() IPV6_V6ONLY Protocol not available* When I try to run any Xclient after this error occurs, *Xserver fails in AllocNewConnection::: **fd[259] lastfddesc[256]* Also Xserver is not ale to launch any client after this error. Note: Before the above mentioned thrift error messages occur, the *fd values *are* 256 *and clients are laucnhed successfully. However, after the thrift error messages occur, *fd value 256 *and clients cannot be launched. * * I am not aware of the complete stack running on the system, hence dont know if any other module is affecting. Could anyone please let me know what could be the issue in getting *fd value256* ? And how I can trace/ fix the issue? Note: I also tried compiling Xserver with IPV6, but I still get the same issue.
