Unreproducible Issues

The following issues have been observed in CA AppLogic releases but are extremely difficult to reproduce (if at all) and have only been observed once or twice. If any of these issues appear on your grid, please send a bug report to CA describing which problem occurred and which CA AppLogic commands were executed that led to the failure.

1. Defect SCR 2842 - Server rebooted due to a crash in the Linux kernel (observed in various releases)

   A server in the grid rebooted on its own due to a crash in the Linux kernel in dom0 of the server. This would not cause the entire grid to fail like in previous CA AppLogic releases; but could cause application downtime. In such a case CA AppLogic restarts the appliances that were running on the failed server on other servers in the grid. If this issue is observed on your grid, contact CA Support.

2. Defect SCR 2834 - Server loses connection to the grid controller

   In CA AppLogic 2.4, there have been several cases where a server loses connection to the grid controller and reboots. This causes all of the appliances that were running on the server to be rescheduled on other servers in the grid and can also cause application downtime. It is unknown why the servers are losing their connections to the grid controller.

   If the server's connection to the grid controller is dissolved, the server tries to reconnect to the grid controller and if successful, the server remains operational and there is no application downtime. If the server cannot reconnect to the grid controller for one minute, the server is rebooted and application downtime occurs. When a server loses its connection to the grid controller, a message is logged to the dashboard. If this problem is observed, contact CA Support.

3. SCR 2903 - Volume resize of 4 NTFS volumes executed at the same time failed

   On CA AppLogic, resizing 4 NTFS volumes at the same time caused all four volume resize operations to fail. This issue has been observed only once.

4. SCR 3289 - NASR replication failure was observed when almost out of disk space

   While NASR was replicating an 800MB file on a 1GB volume, the NASR appliance became unresponsive. CA is unable to reproduce this issue. If this issue is encountered on your grid, contact CA support.

5. SCR 3711 - Opening many graphical consoles crashed a server in the grid

   User opened six graphical consoles to different windows appliances running on the grid (opened at the same time). Upon opening the seventh graphical console, one of the servers rebooted and rejoined the grid. The appliances that were running on the failed server were restarted on other servers within the grid. This issue has only been observed once.
