Technical Articles ID: KB91265
Last Modified: 2021-02-18 19:29:15 Etc/GMT

Environment

McAfee Agent (MA) 5.6.0
Supported Linux operating systems

For environment information, see KB51573 - Supported platforms for McAfee Agent 5.x.

Problem

At random times, a segfault occurs on the McAfee Agent service masvc.

The Messages log (/var/log/) records the error:

<computer_name> kernel: masvc[7690]: segfault at 78 ip 00007fd6ed8c4041 sp 00007ffdf4ef4700 error 4 in libuv.so.0.10[7fd6ed8bb000+24000]

The Masvc_<computer_name>.log records the following error:

594 (3011.3011) icmp.Debug: echo pkg send to repository <server_name>/<2001:480:10:16::11> failed, lets try one more time.

NOTE: Errors are only seen when logging is set to detailed logging in the McAfee Agent policy before debug messages appear in the masvc log.

Cause

This issue can occur when:

The system does not have IPv6 enabled.
And
The McAfee Agent tries to create an IPv6 socket when a name resolution for an IPv6 repository is performed.

Solution

This issue is resolved in McAfee Agent 5.6.1.

Issue resolutions in updates and major releases are cumulative; Technical Support recommends that you install the latest version. To find the most recent release for your product, go to the Product Downloads site.

Our product software, upgrades, maintenance releases, and documentation are available on the Product Downloads site.

Workaround

Restart all McAfee Agent services. Use the following command:

/etc/init.d/ma start

Related Information

This issue was seen with MA 5.6.0, but could potentially occur on earlier versions of MA.

This specific issue only occurs if IPv6 is disabled on the client. To see if any installed network interfaces have IPv6 enabled, run ifconfig -a from a terminal window on the Linux client.
