Cannot communicate with mainApp (getVersion)

MohamedCSE — Sun, 10 Mar 2019 12:07:38 GMT

Hi,

Whenever we apply the signature update to IPS 4215, it reboot itself normal but gives an error after enter the

username/pasword by using ssh; and not enter the CLI.

"Error: Cannot communicate with mainApp (getVersion). Please contact your system administrator.

Would you like to run cidDump?[no]: "

After rebooting the IPS by power off/power on, it works normal, we enter CLI.

So we could not apply the signature update from IPS-sig-S487-req-E4.pkg to IPS-sig-S511-req-E4.pkg.

IPS# sh ver

although when i tried to update the signature agian after the reboot, it gave me the following error:

Error: execUpgradeSoftware : Update IPS-sig-S511-req-E4.pkg is already installed on this system

Any advice about this problem?

Thanks in advance.

Hi ,

It seems like the mainApp has hung on the IPS.

Two known defects which might cause the same : CSCtj86988 and CSCuf20148. However, CidDump and few other debugging outputs are required to investigate this further and would give us a better insight on this. For stability, you may consider an upgrade to 7.1(7) or to the latest version code based on the platform.

To recover the sensor from the hung state, a reload is required.

Hope that answers your query,
