Hi,

Yes the program goes into the infinite loop, Following is the log, which I
have taken using *strace* command, core dump is not able to show anything.
I think there is an internal retry counter, can we set that counter value
by anyhow? please suggest me any solution.

open("/dev/urandom", O_RDONLY|O_NONBLOCK|O_NOCTTY) = 4

fstat64(4, {st_mode=S_IFCHR|0666, st_rdev=makedev(1, 9), ...}) = 0

read(4, "n9\314l\270+\3066\33\366T\3657\262\322<\231\373\\\22\177"..., 32)
