Mysql 5.7 fails to create more than 50 threads
Hi guys,
I'm facing a serious problem with opening new threads.
Currently the structure is active with a master-slave database serving
6,000 simultaneous users.
The demand is high and the flow has been working using cache and opening
few threads.
The query returns are extremely fast.
However, at times it is necessary to open new threads and I am
experiencing a limitation where I cannot create more than 50
connections.
Starts returning "Abort Connection" and crashes the system until thread
flow is free (<50).
We've already checked all the settings for opening new threads and they
seem to be OK, but there's something blocking it that we can't find.
Here are some indices:
max_connections=151
innodb_buffer_pool_size=120G
innodb_log_file_size=36G
innodb_buffer_pool_chunk_size=16G
The slave server has 192G RAM, 24vCPUs.
If you need more details, please ask.
Thank you for your attention!
