gstnvtracker: Unable to acquire a user meta buffer. Try increasing user-meta-pool-size

May i know how i can calculate the user-meta-pool-size, and what will happen if the pool size is insufficient. I added the user-meta-pool-size=512, and the problem still exists. The parameter was added under the tracker config file. Please advise on how to calculate the pool size and am i correct adding the parameter under the tracker config file

You can refer to our Guide Miscellaneous Data Output. When the latency for downstream plugins to release the buffers is too long, the buffer pool may be empty so tracker will skip reporting the miscellaneous data for next batch.
The processing speed of downstream plugins may be slow due to some performance problems.
