java - OutOfMemoryError:GC Overhead limit exceeded -

in 1 of our java application have got outofmemoryerror:gc overhead limit exceeded.

we have used hashmaps in someplaces storing data.from logs can identify reproducing @ same place.

i wanted ask if garbage collector spends more time in clearing hashmaps?

upon looking @ code( cant share here ), have found that there hashmap created

hashmap topo = new hashmap();

but hashmap never used. kind of memory leak in application ?

if hashmap created inside method doing processing , not used elsewhere method accessed multiple threads 20 .then in such case impact,creating hashmap above, garbage collector spend more time in recovering heap , throw oome.

please let me know if need more details.

n 1 of our java application have got outofmemoryerror:gc overhead limit exceeded. have used hashmaps in someplaces storing data.from logs can identify reproducing @ same place.

if hashmap ever building , marked static, means keep adding things hashmap , never delete. 1 fine day lead outofmemoryerror.

garbage collector spends time on objects not referenced, weakly referenced, soft referenced. wherever find such objects, depending on need clear them.

upon looking @ code( cant share here ), have found that there hashmap created hashmap topo = new hashmap(); , hashmap never used. kind of memory leak in application ?

if hashmap created inside method doing processing , not used elsewhere method accessed multiple threads 20 . in such case impact,creating hashmap above, garbage collector spend more time in recovering heap , throw oome.

if hashmap local methid, , method exits after doing processing, should garbage collected method exits. hashmap local method, each thread have separate copy of map , once thread finishes method execution, map eligible gc.
