Hello,
In the last weeks we have detected some problems with AMP connector, in MAC computers and in Windows computers. In both cases the common element is the last version of Google Chrome 95.0.4638.54
Thursday 21/10/2021:
Some MAC computers start restarting randomly, problems with CPU and connectivity issues. After reviewing the system.log of some of the affected we have seen the following errors:
Oct 21 10:33:12 Google Chrome Helper[50032]: Libnotify: notify_register_coalesced_registration failed with code 9 on line 2835 Oct 21 10:30:34 Google Chrome Helper[700]: Libnotify: notify_register_coalesced_registration failed with code 9 on line 283 Also we have found in the second computer a bug detected in Google Chrome by the system
Oct 21 10:30:44 Google Chrome[553]: BUG in libdispatch client: mach_recv, monitored resource vanished before the source cancel handler was invoked { 0x7fe037b30f00[source], ident: 77059 / 0x12d03, handler: 0x113779cb0 }
Also other day in other computer we saw the same errors repeated several times:
Google Chrome Helper[6117]: Libnotify: notify_register_coalesced_registration failed with code 9 on line 2835 Oct 27 08:59:44 — last message repeated 16 times — Oct 27 08:59:44 Google Chrome Helper[6118]: Libnotify: notify_register_coalesced_registration failed with code 9 on line 2835 Oct 27 08:59:45 — last message repeated 16 times — Oct 27 08:59:45 Google Chrome Helper[6121]: Libnotify: notify_register_coalesced_registration failed with code 9 on line 2835 Oct 27 08:59:45 — last message repeated 16 times — Oct 27 08:59:45 Google Chrome Helper[6122]: Libnotify: notify_register_coalesced_registration failed with code 9 on line 2835 Oct 27 08:59:46 — last message repeated 16 times — Oct 27 08:59:46 Google Chrome Helper[6123]: Libnotify: notify_register_coalesced_registration failed with code 9 on line 2835 Oct 27 09:00:16 — last message repeated 14 times — Oct 27 09:00:19 Google Chrome Helper[6123]: Libnotify: notify_register_coalesced_registration failed with code 9 on line 2835
Investigating in Internet, there was some past problems between the two applications but with other Operating System, in this case Dell computers with Windows https://community.cisco.com/t5/endpoint-security/google-chrome-will-not-open-when-amp-is-enabled/td-p/4420348
On the other side,
Some problems were detected in Windows computers and the last version of Google Chrome. They are not able to open the application, and we have no events in the console, but we know that it is AMP as if they disable the connector, Google Chrome starts working.
The summary of the affected computers is the following:
Affected MAC Computers
