Hi Peter I have deployed syslog-ng-3.9.1-1.el6.x86_64 , where I am seeing one issue. Where there is disk usage in greater than 90%, It coredumps.

I have pasted part of core here and attached the coredump full file gdb) bt full #0 0x0000003b52a325e5 in raise () from /lib64/libc.so.6 No symbol table info available. #1 0x0000003b52a33dc5 in abort () from /lib64/libc.so.6 No symbol table info available. #2 0x0000003206c7506b in iv_fatal (fmt=<value optimized out>) at iv_fatal.c:57 ap = {{gp_offset = 8, fp_offset = 48, overflow_arg_area = 0x7f35c5aadac0, reg_save_area = 0x7f35c5aada00}} msg = "iv_init: can't initialize event dispatcher\000\006\062\000\ 000\000\177\000\000\bZ\003\000\000\000\000`KL\234\065\177\ 000\000?M006\062\000\000\000@֪\177\000\000@֪\177\000\000\ 177\000\000\b\000\000\000\000\000\000\000L\234\065\177\000\ 000L\234\065\177\000\000\000KL\234\065\177\000\000Ye006\062\000\000\000\001\ 000\000\000\000\000\000\000ت\177\000\000ت\177\000\000\177\000\000ت\177", '\000' <repeats 46 times>, "\004", '\000' <repeats 35 times>... #3 0x0000003206c76f2a in iv_fd_init (st=0x7f359c945850) at iv_fd.c:129 No locals. #4 0x0000003206c77499 in iv_init () at iv_main_posix.c:74 st = 0x7f359c945850 #5 0x0000003206c75b8e in iv_work_thread (_thr=0x996c540) at iv_work.c:177 thr = 0x996c540 pool = 0x1df6820 #6 0x0000003206c77def in iv_thread_handler (_thr=0x52933d0) at iv_thread_posix.c:142 __clframe = {__cancel_routine = 0x3206c77e50 <iv_thread_cleanup_handler>, __cancel_arg = 0x52933d0, __do_it = 1, __cancel_type = 0} thr = 0x52933d0 #7 0x0000003b53207aa1 in start_thread () from /lib64/libpthread.so.0 No symbol table info available. ---Type <return> to continue, or q <return> to quit--- #8 0x0000003b52ae8aad in clone () from /lib64/libc.so.6 No symbol table info available.
