Dear All,

Fatal Exception:panic in 5 seconds

"Kernet panic - not syncing : Fatal Exception"

Hi Ayma,

This is a rare condition usually seen when the system fails the memory and file system checks. If you reboot it; it should relieve this condition for the time being as more fs checks are done at startup. Depending on your software version, you maybe running into a software bug as there are several bugs with similar symptoms in versions older than 6.0.7. If you haven't already done so, please upgrade your Mars appliance to the latest 6.0.7.

Potential Bug:

/* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;}
