Cisco Bug: CSCum33627 - 'vrrp-eng' process leaks memory during each show run
Feb 15, 2018
- Cisco Nexus 7000 Series Switches
Known Affected Releases
Symptom: The VRRP process ("vrrp-eng") will leak a small amount of memory each time the 'show running-config' or 'show running-config vrrp' commands are executed. The amount of memory leaked on each occurrence will range from a few hundred bytes to a few kilobytes, and will be approximately proportional to the number of interface present on the device. The leak is observed under 'libacfg.so' in the output of 'show vrrp internal mem-stats detail' as below: N5K-A# sh vrrp internal mem-stats detail | grep acfg 6 [r-xp]/isan/plugin/0/isan/lib/libacfg.s 17 25 2380 2921 <----- 51 FU_MEM_fu_global_acfg_init_info_t 0 1 0 12 <execute 'show run'> N5K-A# sh vrrp internal mem-stats detail | grep acfg 6 [r-xp]/isan/plugin/0/isan/lib/libacfg.s 18 26 2520 3061 <----- 51 FU_MEM_fu_global_acfg_init_info_t 0 1 0 12 <execute 'show run'> N5K-A# sh vrrp internal mem-stats detail | grep acfg 6 [r-xp]/isan/plugin/0/isan/lib/libacfg.s 19 27 2660 3201 <------ 51 FU_MEM_fu_global_acfg_init_info_t 0 1 0 12 Should the VRRP process exceed its memory limit, it will crash and cause a reload of the affected switch or supervisor. Conditions: VRRP feature enabled (i.e. 'feature vrrp' is present in the configuration). No VRRP configuration beyond this is required - if the feature is enabled at all the leak will be observed.
