Following up this issue, as we managed to resolve it.
What helped:
- increasing transaction processes amount at least to the recommend (8), better to set their amount the same as the amount of storage processes (for 12 storage processes - 12 transaction processes)
- giving storage processes more memory, particulary it should be at least 12Gib for our load, perfectly 16Gib
- as a side note, on the servers with not as many memory available, when configuring, transaction processes doesn’t require more than 4-5Gib of RAM configured
- if you have 8Tb and more disks, it’s better to split it up to smaller disks of 4Tb, as mentioned in the documentation
What we tried but didn’t help:
- decreasing load on the foundationdb
- disabling huge pages (offered in one solution here)
