Hi,

 

Hope you are doing well.

 

Along with this failed GAM update, you should also be seeing GAM service crashing.

 

You should see below kind of messages in /var/log/messages:-

Jul  8 10:48:49 mwgappllab systemd[1]: Got notification message from PID 1375, but reception only permitted for main PID 3066
Jul  8 10:48:49 mwgappllab systemd[1]: Got notification message from PID 1375, but reception only permitted for main PID 3066
Jul  8 10:49:55 mwgappllab kernel: [168185.431214] traps: gamserver[1377] trap invalid opcode ip:7fda4f8c7a62 sp:7fda695d9490 error:0 in vcpu_zsim.so[7fda4f7d0000+557000]

this is a known issue with GAM 2019
 
The crash is caused by the ZSIM library. The loading order in v2019 has changed compared to v2017.
 
 
 
This will be fixed in v2019 build 3726.
 
 
 
 
Fixed build is available to affected customers via "uc-beta" update channel for now.
 
 
 
Alternatively customer can also downgrade to GAM 2017 if you dont want to make use of uc-beta
 
 
 
Rollback to GAM 2017 can be done  using  ud-rollbackGAM2017 parameter
 
 
Take MWG GUI->Navigate to option Configuration->Select the appliance->Central Management->Advanced Update Settings->Enter a special custom parameter sequence for an update server->  Add ud-rollbackGAM2017      to get  GAM 2017
 
 
 
Attaching screenshots for reference.  After making above change trigger an manual update.

Hi, @aloksard 

We have MWG 7.8.2.3 (26967) - this solution is applicable for it?
