[opencms-dev] Search Index locked

[Andras Balogh]

Hello,

I had an OutOfMemory error when publishing and indexing a site, there 
were some big PDFs.
The Search Index is somehow locked but I don't know how to unlock it.
On every publish I get this message:
Index "Online_en" is currently locked an can not be updated. Waiting 10 
seconds for lock release.
.....
Index "Online_en" is currently locked an can not be updated. Waiting 1 
seconds for lock release.
Unable to obtain lock for index "Online_en". Giving up.

This is in Opencms6.2.2

Can You help me how can I unlock the Search Index?

Best regards,
Andras
