[Koha] Koha presents an error, and no longer shows the cataloged records after a search

[Victor Barroso Oliveira]

Good Morning,
After a time of using several operators, Koha presents an error, and no
longer shows the cataloged records after a search.
Only after the server restarts does the records appear again in a search.
Following are log files that are in the var / log / koha folder
How can I solve this?
Thank you,
Victor
