Error Insufficient Memory Reserved For Statement
'm getting this error: ERROR: insufficient memory reserved for statement (memquota.c:228) when I run this query on my GPCE 4.1.1.1 instance on a table with 760 partitions (one for each day of a couple of years): select count(1) from mytable; The same query works on another table with the same data and no partitions. I can work around the issue by issuing several queries over a limited range in the table and adding up the results. This seems to suggest that the number of partitions is related to the issue. Also, I have two tables with the same date range and number of partitions, one with only 15M rows, and the other with 350M rows. Both have the same issue with the above query - which also suggests that the problem is with the number of partitions. Of course, someone will suggest "reduce partitions". Even if I increase the size of the partitions, we'll eventually have this many partitions when we have more data. I'm running on Red Hat Enterprise Linux 5.7 on a 6 CPU machine with 32GB physical memory. I haven't changed any params in the postgresql.conf file. Any suggestions on how to get this query to run?

"When scanning a highly partitioned table with low reserved memory that was set by memory quota, an insufficient memory reserved error can appear. Work-around: Increase the reserved memory increasing statement_mem or increasing the limits of a resource queue. Use statement_mem to set a memory limit for a query. When gp_resqueue_memory_policy is enabled, statement_mem replaces work_mem. The default is 125MB." I ran these statements to get past the issue: set max_statement_mem='3GB'; set statement_mem='2GB'; select count(1) from mytable; This completed on the 750-partition table with 350M rows in 559 seconds. vfisher September 10, 2012 18:11 0 votes Share Facebook Twitter LinkedIn Google+ Permalink © Pivotal

I suggest you to simplify the query statement as possible as you can, and increase the max server memory inthe meantime.

When I attempt to create an object on the heap and there's insufficient memory to do so, the JVM creates an java.lang.OutOfMemoryError on the heap and throws it to me. So implicitly, this means error insufficient memory that there is some memory reserved by the JVM on startup. What happens when this reserved memory is used up (it would definitely be used up, read discussion below) and the JVM does not have enough memory on the heap to create an instance of java.lang.OutOfMemoryError? Does it just hang? Or would he throw me a null since there's no memory to new an instance of OOM ? try { Object o = new Object(); // and operations which require memory (well.. that's like everything) } catch (java.lang.OutOfMemoryError e) { // JVM had insufficient memory to create an instance of java.lang.OutOfMemoryError to throw to us // what next? hangs here, stuck forever? // or would the machine decide to throw us a "null" ? (since it doesn't have memory to throw us anything more useful than a null) e.printStackTrace(); // e.printStackTrace() requires memory too.. =X } == Why couldn't the JVM reserve sufficient memory? No matter how much memory is reserved, it is still possible for that memory to be used up if the JVM does not have a way to "reclaim" that memory: try { Object o = new Object(); } catch (java.lang.
