#321 GTM_Standby crash

[Koichi Suzuki]

GTM standby crashes in the normal operation. Cluster consists of two gtm proxies, two datanodes and two coordinators. The operation is as follows:

i) Initialize each coordinator/datanode with initidb,
ii) Edit configuration files (gtm, gtm_standby, gtm_proxy, coordinators, datanodes) manually (in fact, using dedicated script)
iii) Start all the gtms
iv) Create NODE, create database
v) sql -c 'select 1'

The backtrace looks like:

This might have been fixed by the series of patch by Andrei. Thanks Andrei!! We should continue to see if the similar problem occurs in the future.
