hi samba ,

the issue occurs because computer not have sufficient memory complete requested operation .

this situation occur when 1 or more of following conditions true :
• a report large or complex .
• the overhead of other running processes high .
• the physical memory of computer small .

we can reduce memory consumption redesigning report queries in following ways:
• return less data in report queries.
• use better restriction on clause of report queries.
• move complex aggregations data source.

there similar issue , can refer following kb article:
