Apache 100% cpu when save record and error 500

Hi all,
I have this problem with our instance of SuiteCRM (version 7.11.2):
When user save a record, the operation fail with error 500.
int top, Apache2 use 100% of CPU.
in Admin --> Studio --> Schedulers
for the schedulers : “Perform lucene index” and “Optimize AOD index”
the state of the last execution is “running”

I think that this is the problem or this is connected with my problem

can someone help me?

thank you

If you set all Scheduler Jobs to Inactive and Restart Apache. Do you still get 500 error?
Is there anything in PHP error log? Also Suitecrm.log ?

Which module record save action triggers this? have you checked on other modules ? Are there any logic hooks on the save of this Module? Can you disable those and check again ?

thank you for your reply.
I try with differents modules: Accounts, Contacts Documents etc.
I update from DB into job_queue table the status (set done) of this 2 schedulers, and than it is possible to save without problems.
But if I try to search an account using search bar top left, (using aod search), I can’t fine the account. If I use standard search, it works fine.

I think this second problem is connected to the first one.
