I could finally capture the truss output.
The system() is failing at ioctl() with error EIO, and there is a SIGHUP due to
this.
[b]EIO = Some physical I/O error has occurred[/b]
Can anyone tell me why this error occurrs, and also all system calls fail
because of this error, till the process is retarted?
Thanks in advance!
