crash at recovery #378

akumuli database 96x4GB I'm trying to get data out with a join request with 6 terms. The database is working for a while, but gives 0 data out and just terminates and not accessible through port 8181. Restarting akumulid - it takes about 30 minutes to recover the database, but at the end of a seemingly successful recovery it reports: 2020-11-16 11:11:48,715 [0x7fed3abff700] Main [ERROR] Error executing query 2020-11-16 11:11:48,715 [0x7fed3abff700] Main [ERROR] all VALUES must have the same number of terms 2020-11-16 11:11:48,715 [0x7fed3abff700] Main [ERROR] Terminating (core dumped)

and starts a new recovery. What can be done?

I should add - akumuli version v0.8.80.

The database does not recover. The repair cycle is interrupted by the error above and restarts until same error again.

after about 20 attempts to restart the database seems to run. But this does not change the fact that the damage was caused by a simple PULL request and it may happen again. How can I retrieve information from this database without crashing it?
