[ADMIN] lock problem

[Rural Hunter]

I'm seeing connection hang issue these days. many concurrent connections are hanging on db. They basically do the same thing: update different rows in same table. The sql itself should run very fast as it's updating just one row based on an unique key. I though it might be lock problem.?0?2 The I list the locks ordered by query start time(see list below).?0?2 I'm confused why the oldest connection are still waiting for the lock? anything else can hold that lock? ?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2?0?2 |?0?2?0?2?0?2 1580056836 | ShareLock?0?2?0?2?0?2?0?2?0?2?0?2?0?2 |
