Zabbix server keeps restarting - Cache Size?

[MuriloHB]

Hello guys!

So I'm facing some issues regarding lack of cache on Zabbix and I can't seem to figure it out why... The server keeps shutting down after about 5 minutes.
This is the message I'm getting when looking at the logs:

  2270:20191119:214628.812 [file:vmware.c,line:92] __zbx_mem_malloc(): out of memory (requested 269 bytes)

I've already increased VMwareCacheSize on zabbix_server.conf ( /etc/zabbix/zabbix_server.conf )
Those are my current configurations regarding cache size:

### Option: VMwareCacheSize
#       Size of VMware cache, in bytes. Shared memory size for storing VMware data. Only used if VMware collectors are started.
#
# Mandatory: no Range: 256K-2G Default:
 VMwareCacheSize=250M

### Option: CacheSize
#       Size of configuration cache, in bytes. Shared memory size for storing host, item and trigger data.
#
# Mandatory: no Range: 128K-8G Default:
 CacheSize=64M
### Option: CacheUpdateFrequency
#       How often Zabbix will perform update of configuration cache, in seconds.
#
# Mandatory: no Range: 1-3600 Default:
 CacheUpdateFrequency=60

# Mandatory: no Range: 1-100 Default: StartDBSyncers=4
### Option: HistoryCacheSize
#       Size of history cache, in bytes. Shared memory size for storing history data.
#
# Mandatory: no Range: 128K-2G Default: HistoryCacheSize=16M
### Option: HistoryIndexCacheSize
#       Size of history index cache, in bytes. Shared memory size for indexing history cache.
#
# Mandatory: no Range: 128K-2G Default: HistoryIndexCacheSize=4M
### Option: TrendCacheSize
#       Size of trend cache, in bytes. Shared memory size for storing trends data.
#
# Mandatory: no Range: 128K-2G Default: TrendCacheSize=4M
### Option: ValueCacheSize
#       Size of history value cache, in bytes. Shared memory size for caching item history data requests. Setting to 0 disables value cache.
#
# Mandatory: no Range: 0,128K-64G Default: ValueCacheSize=8M

I've also tried to increase the CacheSize to 64M but it doesn't seem to work aswell. Am I missing something??

Thanks for the help!
