[Koha] Zebra stops every day

[Javed Sahil]

Hi All,

I am using Koha17.11, I moved my old DB which was working fine in koha16.11,

But now my zebra server stops daily or after two or three days,  actually
i have not noted exact duration.

I come to know this error when I see no results in opac search and in About
Koha page there is an Error Message saying,

"Zebra server seems not to be available, is it started? "

Then I issue command,

Koha-restart-zebra library

And it works fine.

But why should i issue the command again  and again.

Any solutions?

Regards,
