ASM Signature Update (ASU) and other Update Check services may fail due to an overload on the F5 download server.
ASU and other Update Check services fail.
-- Automatic update attempt is initiated during specified schedule. -- F5 download server is overloaded by Update attempts.
To work around this issue, run manual updates instead. To prevent this issue, change the time of the daily job run. To do so, follow these steps: 1. Open the cron job text file. # vi /etc/crontab 2. Change this line as follows: From: 02 4 * * * root run-parts /etc/cron.daily To: 10 4 * * * root run-parts /etc/cron.daily 3. Save the changes, and quit vi. This will change the automatic updates to run at 4:10 rather than 4:02.
ASU and other Update Check services now stagger download attempts to prevent F5 download server overload.
