Please find my below deployed environment:

Environment: Microsoft Azure
OS: CentOS 7.0 (64 bit)
FreeSwitch Version: 1.6.6~64bit ( 64bit)

I installed FreeSwitch through "Yum" and works fine for couple of hours. After that I am getting below errors:

[ERR] switch_core_sqldb.c:587 NATIVE SQL ERR [attempt to write a readonly database]
BEGIN EXCLUSIVE
2016-04-05 13:29:33.368355 [CRIT] switch_core_sqldb.c:1952 ERROR [attempt to write a readonly database]
2016-04-05 13:29:33.368355 [ERR] switch_core_sqldb.c:587 NATIVE SQL ERR [cannot commit - no transaction is active]

Can anybody tell me what could be the issue and how to solve this?

Thanks in advance,
Chandra.
