Transaction cache is too full

Hello,

Sometimes I get error from my own node when sending transaction: FAILURE_TRANSACTION_CACHE_TOO_FULL. Is there any way to extend the cache, or is this a network cache?

Are you sending a lot transaction in short time? How many if yes?

No, not many

So maybe your node stop syncing and has not enought memory? Could you paste your start script (runNis) file content?

Start script is default, with initial heap size of 512M and maximum 3200M

Looks like your node is in fork. I would try remove node database and sync from scratch.
Db is located in <USER_DIR>/nem/nis/data

But this problem occurs not often

So after node restart it’s synced with network and works correctly?

Actually yes, but i want to know the cause of this error
