[Building Sakai] Samigo on 2.9.2 veery low ..eventually grinding site to a halt

[David Wafula Wanyonyi]

Dear all,
Since last night we are experiencing very poor performance of Samigo on 2.9.2. Over 900 students were trying to submit and this exhausts all the Thread and DB pools, affectively freezing the servers. The assessment in question has a Grading setting for  immediate submission of grades to gradebook.
Has anyone experienced this ?
Regards,
david.
