Solution

Only the HIPR2 card slot 1109 is rebooting, so it is cutting the bus A connectivity.
The DSM card 2115 is also suspicious, it rebooted many times but for some reason it stopped the 12/04/2017.

The HIPR2 card 1109 must be replaced.

Once the IMT bus A is stabilized, run these commands

- clr-imt-stats:all=yes
Wait for 30 min
- rept-imt-lvl1:r=full:sloc=1201:eloc=1115:filter=erroronly
- rept-imt-info:report=hipr2err:sshelf=1100:sslot=1:eslot=18:sbucket=0
- rept-imt-info:report=hipr2err:sshelf=1200:eshelf=2300:sslot=1:eslot=18:sbucket=0
- rept-imt-lvl2:sloc=2101:eloc=2118:loc=2115
