zmdc crash

[kovaga]

Hi list,
following a pretty standard apt dist-upgrade, my zoneminder is not operational anymore.

zmc and zma processes crash
with the following in the zmdc.log

11/27/2019 19:49:52.460812 zmdc[3185].INF [ZMServer:692] ['zma -m 2' crashed, signal 134]
11/27/2019 19:49:52.470776 zmdc[3185].INF [ZMServer:692] ['zmc -m 2' crashed, signal 134]
no memkey in zmMemInvalidate
no memkey in zmMemInvalidate
no memkey in zmMemInvalidate
no memkey in zmMemInvalidate

if I start the processes manually, i get the
# root@homenas  /var/log/zm  zma -m 2
double free or corruption (out)
[1] 2965 abort (core dumped) zma -m 2

✘ root@homenas  /var/log/zm  zmc -m 2
double free or corruption (out)
[1] 3047 abort (core dumped) zmc -m 2

Amongst the packages that were upgraded is
mysql-server-5.7:amd64 (5.7.27-0ubuntu0.18.04.1, 5.7.28-0ubuntu0.18.04.4)

Any ideas on where to dig?

Solved by upgrading to 1.33.14.

Just wanted to post that I ran into this same problem over the weekend and spent way too many hours trying to find the cause. Like you, I saw that mysql had been updated and immediately assumed that was my problem. Manually running zmc gave me the same "double free" crash you mentioned. I "fixed" it by restoring my system from a level 0 dump that I made before the updates were applied. I wasn't ready to take the jump to 1.33 just yet. I have a number of ZM 1.32 servers running on Ubuntu 18.04 and this is going to make me reluctant to apply updates. Hopefully someone can provide some additional info on this problem.
