We have one issued ePMP 1000 NonSynced Connectorized 120°Sector AP, Number of connected SM: 42 SMs are disconnecting in groups. Count of disconnected SMs is sometimes 5 or 10 or 18 (it is various). The period of time dropped is 2-3 times a day. AP software version: 2.5, SMs sofware version: 2.4.3 or 2.5.1.
I tried to upgrade the AP to 2.6.1, but after that, the AP rebooting randomly so i downgrade it back to 2.5. I already changed the frequency. Debug log is clean, AP logfiles is also clean. I have noticed also strange situation - when you check AP-Monitor-Wireless , you see, that SM is connected to the AP, but there is no response from it. After few minutes it response normally.
There is only 3 sectors (Ubiquiti) and 1 issued ePMP sector on the site. Do you have any ideas where can be a problem?

I checked all of the SMs, but there is no messages like you showed me.
This is the specific uptime statistics. AP uptime is: 17hours. Connected SMs: 40
19 SMs: session uptime: 17hours , device uptime 17hours (System statistics of this group: Session drops:0, Device Reboots:0)
9 SMs: session uptime: 9hours, device uptime 17hours (System statistics of this group: Session drops:1, Device Reboots:0)
3 SMs: session uptime: 8hours,, device uptime 17hours (System statistics of this group: Session drops:2, Device Reboots:0)
9 SMs: session uptime: 3hours,, device uptime 17hours (System statistics of this group: Session drops:2, Device Reboots:0)
Right now, i see that SMs is connected to AP, i tried randomly ping it - some of them response me and some of them not, after few minutes all of them fully response. I really dont understand where can be a problem.
