OutOfMemoryError in Persistent Cache

[FlareBlitzV]

I am trying to dump the data from a heap(in memory) cache to disk cache via iterator, this happens every 30 mins. While trying to do that getting Out of Memory. Not sure if this is due to cache corruption. Once the OutOfMemoryError occurs, the program restarts and while the cache initialized there is no error. But when the data is fetched from the cache OutOfMemoryError is thrown again.
Note: Both heap and disk cache are created with ehcache as two separate caches.

Ehcache Version: 3.8.1
OS: Windows 10
JDK: ZuluJDK_8_0_322

Cache Configuration:

persistentCacheManager = (PersistentCacheManager) CacheManagerBuilder.newCacheManagerBuilder()
.with(CacheManagerBuilder
.persistence(ehCacheData.getDiskStoragePath()))
.withCache(ehCacheData.getCacheName(), CacheConfigurationBuilder
.newCacheConfigurationBuilder(String.class, ArrayList.class,
ResourcePoolsBuilder.newResourcePoolsBuilder()
.disk(450L, MemoryUnit.MB, true)))
.build(true);

Code Snippet:
Iterator<Cache.Entry<String, ArrayList>> iterator = heapCache.iterator();
while (iterator.hasNext()) {
Cache.Entry entry = (Cache.Entry)iterator.next();
diskCache.put(entry.getKey(),entry.getValue());
}
heapCache.clear();

Exception Stack trace:
Failed to allocate direct buffer for FileChannel read. Consider increasing the -XX:MaxDirectMemorySize property to allow enough space for the FileChannel transfer buffers|

Found the below exception later while trying print the data from the disk cache:

Kindly help me regarding this. Thank you.

Is there any chance that the cache was corrupted due to antivirus and is causing the following exception. Can anyone help me regarding this. Thank you
