I can provide query if needed

Can you confirm the version that you are using by running the following query show variables like 'memsql_version'? 5.5.5 is a 4 year old version and has been out of support for 2 years.

memsql>show variables like ‘memsql_version’;
±---------------±------+
| Variable_name | Value |
±---------------±------+
| memsql_version | 5.5.5 |

Ok, I’d strongly recommend upgrading to the latest version as it will most likely fix your crash.

There is no other way rather upgrade ?

That’s correct. There have been 4 years of feature development and bug fixes since 5.5 was released so you will be able to get some really great improvements when you upgrade.
