dbcache flush issue

HCL Notes/Domino 8.5 Forum (includes Notes Traveler)

Subject: dbcache flush issue

Feedback Type: Problem

Product Area: Domino Server

Technical Area: Administration

Platform: Linux server

Release: 8.5

Reproducible: Always

I having some issue when I send "dbcache flush" to Domino server console.

When I type dbcache flush, my domino console executes the commands and after 1 minute my console does not accept any command like "show server", "show tasks" ..., and I have to wait aprox 40 minutes waiting consoles backs to normality (normality = accepts comands in real time).

Sometimes, console gives to me a message like " No response from server for this command".

I opened a PMR so, they didn´t discover anything. I asked about changing the NSF_Dbcache_MaxEntries but the analyst said that I could have more delay in sending dbcache flush to the console.

I have 2500 users running in a Lotus Domino 8.5 with Language Pack Pt-Br.

I would like to know if someone in this forum having this issue with dbcache too...
