Symptom
- A user connection dies unexpectedly.
- The ASE errorlog contains a signal 11 error in the module senddone() followed by a stack trace:
-
Current process (0x1f23082a) infected with signal 11 (SIGSEGV)
Address 0x0x000000000185ca7b (senddone+0xc2b), siginfo (code, address) = (1, 0x0x00000000deadbbae) - Stack trace includes functions:
senddone
s_cleanframe
exc__raise
...
curs_fetch
or
curs_open
Note: A full stack trace is available under Attachments.
- Checking the values of the registers in the "Saved signal context" area of the stacktrace in the errorlog one (probably RAX) will contain the value 0x00000000deadbabe.
